Metal-free tooth-supported FDPs (pressed veneering ceramic) vs Metal-free tooth-supported FDPs (layered veneering ceramic)

Aesthetics · Adults (18 years or older) needing a three-unit tooth-supported fixed dental prosthesis

  • Metal‐free materials for fixed prosthodontic restorations 2017 · Cochrane All outcomes
    No comparative data were presented with regard to aesthetics. Aesthetics evaluated by the patient was reported dichotomously (yes/no) in the trial but no between-group estimate was presented.

Metal-free implant-supported FDPs (zirconia-toughened alumina; In-Ceram Zirconia) vs Metal-free implant-supported FDPs (yttria-stabilized tetragonal zirconia; Denzir)

Aesthetics · Adults (18 years or older) needing an implant-supported fixed dental prosthesis in the posterior region

The review found no eligible studies for this question.

Metal-free cantilevered FDPs (feldspathic-veneered zirconia) vs Metal-ceramic cantilevered FDPs

Aesthetics evaluated by the patient · Adults (18 years or older) needing replacement of one premolar or incisor with a cantilevered fixed dental prosthesis

It is very uncertain whether metal-free cantilevered FDPs (feldspathic-veneered zirconia) changes aesthetic evaluation (patient VAS) compared with metal-ceramic cantilevered FDPs (very low certainty).

Metal-free FDPs (zirconia ceramic) vs Metal-ceramic FDPs

Patient satisfaction (measured by patient satisfaction or aesthetic scales) · Adults (18 years or older) needing a three-unit fixed dental prosthesis (FDP)

It is very uncertain whether metal-free FDPs (zirconia ceramic) changes aesthetic evaluation (patient aesthetic satisfaction changes) compared with metal-ceramic FDPs (very low certainty).
